Disallow anonymous functions and classes as the default export

💼 This rule is enabled in the following configs: ✅ recommended, ☑️ unopinionated.

💡 This rule is manually fixable by editor suggestions.

Naming default exports improves codebase searchability by ensuring consistent identifier use for a module's default export, both where it's declared and where it's imported.

Examples

// ❌
export default class {}

// ✅
export default class Foo {}

// ❌
export default function () {}

// ✅
export default function foo () {}

// ❌
export default () => {};

// ✅
const foo = () => {};
export default foo;

// ❌
module.exports = class {};

// ✅
module.exports = class Foo {};

// ❌
module.exports = function () {};

// ✅
module.exports = function foo () {};

// ❌
module.exports = () => {};

// ✅
const foo = () => {};
module.exports = foo;
